Prerequisites and Toolkit

To follow this implementation, you should be comfortable with the

framework and basic terminal operations.

Key Libraries & Tools

Plans reside in config/spark.php. Here, you define your monthly and yearly IDs—which you fetch from your

Tailwind CSS

classes. To link users to the portal, simply point a navigation link to the /billing route defined in your configuration.
